RESUMO
BACKGROUND: Strictures of the urethra are the most common cause of obstructed micturition in younger men and frequently recur after initial treatment. Standard treatment comprises internal widening of the strictured area by simple dilatation or by telescope-guided internal cutting (optical urethrotomy), but these interventions are associated with a high failure rate requiring repeated treatment. The alternative option of open urethroplasty whereby the urethral lumen is permanently widened by removal or grafting of the strictured segment is less likely to fail but requires greater expertise. Findings of Improved choice of graft material and shortened hospital stay suggest that urethroplasty may be under utilised. The extent and quality of evidence guiding treatment choice for this condition are uncertain. OBJECTIVES: To determine which is the best surgical treatment for male urethral stricture disease taking into account relative efficacy, adverse event rates and cost-effectiveness. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register (searched 21 June 2012), CENTRAL (2012, Issue 6), MEDLINE (January 1946 to week 2 June 2012), EMBASE (January 1980 to week 25 2012), OpenSIGLE (searched 26 June 2012), clinical trials registries and reference lists of relevant articles. SELECTION CRITERIA: We included publications reporting data from randomised or quasi-randomised controlled trials comparing the effectiveness of dilatation, urethrotomy and urethroplasty in the treatment of adult men with urethral stricture disease. DATA COLLECTION AND ANALYSIS: Two authors evaluated trials for appropriateness for inclusion and methodological quality. Data extraction was performed using predetermined criteria. Analyses were carried out using the Cochrane Review Manager software (RevMan 5). MAIN RESULTS: Two randomised trials were identified. One trial compared the outcomes of surgical urethral dilatation and optical urethrotomy in 210 adult men with urethral stricture disease. No significant difference was found in the proportion of men being stricture free at three years or in the median time to recurrence. The second trial compared the outcomes of urethrotomy and urethroplasty in 50 men with traumatic stricture of the posterior urethra following pelvic fracture injury. In the first six months, men were more likely to require further surgery in the urethrotomy group than in the primary urethroplasty group (RR 3.39, 95% CI 1.62 to 7.07). After two years, 16 of 25 (64%) men initially treated by urethrotomy required continued self-dilatation or further surgery for stricture recurrence compared to 6 of 25 (24%) men treated by primary urethroplasty. There were insufficient data to perform meta-analysis or to reliably determine effect size. AUTHORS' CONCLUSIONS: There were insufficient data to determine which intervention is best for urethral stricture disease in terms of balancing efficacy, adverse effects and costs. Well designed, adequately powered multi-centre trials are needed to answer relevant clinical questions regarding treatment of men with urethral strictures.

AIM: An ageing population is at significant risk of developing of renal cell carcinoma (RCC). We evaluate our units experience in managing RCC in octogenarians using either laparoscopic or open radical nephrectomy, highlighting the postoperative complication rates and survival outcomes. MATERIALS AND METHODS: From June 2001 to June 2008, 65 octogenarians underwent a radical nephrectomy for suspected renal cell carcinoma. The procedure was performed laparoscopically (group 1) in 29 patients (44%) and via an open nephrectomy (group 2) in 36 patients (56%). The presenting age, sex distribution, ASA score, preoperative co-morbidities and indications for nephrectomy were statically comparable in both groups. Postoperative complications were recorded using the Clavien-Dindo classification. RESULTS: Both groups were similar preoperatively with respect to age of presentation, ASA score and co-morbidities such as hypertension, ischemic heart disease, and chronic respiratory disease. Group 1 showed better statistically significant operative parameters (operative time and blood loss), mean length of hospital stay and most importantly postoperative complications. Postoperative complication rates were lower in group 1 (48.3%) when compared with group 2 (80.5%) (p<0.05). CONCLUSION: Surgery for renal cancer in patient over the age of 80 should only be considered after a thorough work up. Chronological age itself should not be the only determining factor. If such a surgery was to be undertaken, then in our experience, patients who underwent laparoscopic radial nephrectomy had fewer complications than those had open radical nephrectomy.

OBJECTIVE: To audit our results of dorsal buccal mucosal graft urethroplasty for recurrent bulbar urethral stricture disease and compare them with those from specialist centres. PATIENTS AND METHODS: Data were collected prospectively on 52 men who had urethroplasty with > or =1 year of follow-up; failure was defined as the need for further intervention. RESULTS: The mean (range) age of the patients was 39 (19-61) years and 23 (45%) had an identifiable cause for their stricture. The mean (range) stricture length was 3.5 (1.5-6) cm and was associated with moderate or severe spongiofibrosis in 38 (73%) men. Ten (19%) men had minor complications after surgery. The mean (range) follow-up was 34 (12-80) months, with the mean maximum urinary flow rate increasing from 6 to 24 mL/s after surgery. The surgery failed, requiring dilatation or urethrotomy, in seven (14%) men at a mean (range) of 25 (15-50) months after urethroplasty, giving an overall success rate of 86%. CONCLUSION: This prospective audit of dorsal buccal patch augmentation urethroplasty for bulbar strictures shows an equivalent outcome to the standard set by the expert originators, suggesting that is transferable to less specialized centres. The efficacy, low complication rate, short hospital stay and general applicability of the technique encourage its use for all men with recurrent bulbar stricture disease, but formal comparison with other options in randomized trials, including cost-effectiveness analysis, is needed.

The interpretation of QT interval is often neglected during electroencephalography (EEG) reading. We compared the incidence of prolonged QT interval, as seen in the electrocardiography (ECG) recording lead of the EEG, in children presenting with seizure, syncope, or attention-deficit hyperactivity disorder (ADHD). Abnormal QT was defined as >460 ms. The incidence of prolonged QT in the seizure, syncope, and ADHD groups was 1/50 (2%), 7/50 (14%), and 2/50 (4%), respectively (P = .036, chi-square). The mean +/- SD of QT were 405 +/- 34, 424 +/- 39, and 414 +/- 36, respectively (P = .035, analysis of variance [ANOVA], syncope group, compared with seizure group). The incidence of prolonged QT as measured in the EEG was unexpectedly high in children presenting with seizure, syncope, or ADHD. These data support the concept that QT evaluation should be emphasized during routine EEG reading, as it may aid in identifying cases of undiagnosed cardiac conduction abnormalities. Prospective studies comparing EEG-ECG tracings with 12-lead ECG are warranted.
